How long should it take Disk2vhd to convert Windows 2012 server?

Hi

We are trying to P2V a Windows 2012 server for the first time. The source server is a domain controller/file server for a school. When we run disk2vhd it seems to take an age to convert the disks. It's currently estimating just under 2 days to complete the conversion.

Disk2vhd times are dependent on partition size (not space used) and disk I/O speeds in addition to network speeds. Disk2 VHD over a gigabit network (which is slow compared to disk speeds on a local system) and large partitions, days is not out of the question.

I was able to use that tool to migrate a client environment in a few hours; it is surprisingly zippy.

Thanks Cliff. The parition sizes are 147GB and 1892GB, so that might explain the lag. I assumed it would ignore unused space during the conversion.

Since the second, larger drive is predominately profiles and user data a better approach might be just to convert the C: drive, then manually copy the data over. I was probably being a bit ambitious trying to squeeze it into one task.
